There are many wondrous, enigmatic and fascinating attractions on the Big Island of Hawaii, some better known than others, many out of the way and generally off the beaten track. Tour Guide Hawaii has produced an encyclopedic collection of the most up-to-date information, presented as short GPS-cued videos, in an app downloadable to iPhone and iPod Touch that covers the entire Big Island, highlighting the popular and the uncrowded, the famous and the secluded, the adventurous and the relaxing.

Pu’u Pua’i, which means “gushing hill”, is a cinder cone perched atop the rim of Kilauea Iki. At Pu’u Pua’i Overlook an incredible view of Kilauea Iki, which means “Little Kilauea” spreads beneath you. Eruptions of Kilauea Iki in 1959 followed almost a century of quiescence and produced fire fountains exceeding 1900 feet—the highest on record anywhere. The overall eruption proceeded in “spurts” of activity—brief eruptive events separated by times of quiet–which produced enough lava and airfall material to bury a football field 15 inches deep every hour (about two million tons of lava per hour). However, in between eruptions the lava drained back into the vent, only to be ejected again and again over the 36 day life of the eruption.

Today, the mile-wide cooled and solid surface of the lava lake, tucked 400 feet below the crater rim, is cracked and undulating, pocked and tiled in tilted pahoehoe blocks, issues steam from many vents. Crossing the crater floor on this surface provides one of the most interesting hikes in the Park. Looking up from the bottom of the crater, one can see the distinctive “ring around the crater” marking the high point of the lava lake during the last eruption. Hot, liquid rock still roils only a few hundred feet below the hardened modern surface of the crater floor.

Distances are difficult to comprehend here, unless you see hikers on the trail, across the rim or on the crater floor for scale. Once you have an idea of the magnitude of this crater, bear in mind that the fire fountains in the 1959 eruptions, at their peak, reached about four times the height of the current crater walls.

It is both extremely unsafe and ecologically unsound to visit the actual summit of Pu’u Pua’i. The entire Devastation Trail area is an outdoor laboratory in forest regeneration after the devastating burial in hot air fall material. Please stay on designated trails and do not wander out across the cinder landscape; you will destroy delicate plant life and interrupt soil-forming process, disturbing the natural laboratory.

Mauna Ulu, or “growing mountain” is a still steaming, tall, shield-shaped hill formed by numerous eruptions along the rift between 1969 and 1974. Mauna Ulu is best seen by walking beyond the parking lot to where the end of road is covered in fresh lava flows. At Mauna Ulu, visitors can get an intimate look at both pahoehoe and a’a lava flow types.

Pahoehoe, the less viscous and generally hotter liquid flow, moves fluidly like a river or glacier, the surface folding and molding, like poured taffy, into a ropey structure. Pahoehoe forms generally flat, fairly smooth, hard surfaces. A’a, on the other hand, is much cooler and has exolved much of its dissolved gas, so it is much more viscous, causing the upper surface to fracture into clinker-like boulders and fragments. Flowing a’a sounds and looks like a moving pile of hot glass shards; when it cools, it leaves behind rubbly piles of sharp fragments. Fields of pahoehoe and a’a make a landscape that look as if Madame Pele has bulldozed her land to flat surfaces, but left these acres of boulder piles here and there.

The hike to the summit of Mauna Ulu is fabulous and rewarding. However, it is a long, dry, serious hike with some dangers (rock fall, crater collapse, scalding steam and others) and should only be undertaken by those in good physical condition and experienced at hiking cross-country across broken and hazardous ground.

Aerial view of Pu'u Huluhulu, Hawaii Volcanoes National Park: Photo by Donald B MacGowan

Pu’u Huluhulu (“shaggy hill”) is a 150 foot tall cinder cone formed in pre-contact times between Mauna Ulu and Pauahi Crater. There is a fascinating 3 mile round trip hike from the Mauna Ulu parking lot to the top of Pu’u Huluhulu that is marked by cairns (or “ahu”). The round trip hike from Mauna Ulu Parking lot to Pu’u Huluhulu and return takes about an hour and a half to two hours. From the vantage point of Pu’u Huluhulu’s summit are fine views of Mauna Loa, Kilauea, Mauna Kea, the coastline and the very interesting, active cinder cone, Pu’u O’o (hill of the bird”), about 5 miles away.

Pu’u O’o was built by the fire-fountains erupting along Kilauea’s rift zone between 1983 and 1986. Since 1986, the center of eruption has moved about 2 miles further down the rift to a vent called “Kupaianaha”, or ”mysterious” in Hawai’ian. However, within the maw of Pu’u O’o is an active lava lake, which serves as a window into the plumbing of the eruptive rift system.

Kilauea Iki, meaning “little Kilauea”, is the still seething remnant of a quite recent (1959), spectacular eruption that filled the crater with a molten lake of lava and threw fire fountains as much as 1900 feet in the air. For a sense of scale, the world’s tallest building, the Taipei 101 which is 101 stories tall and 1667 feet high, would be dwarfed by these fire fountains.

Distances across the crater are hard to guess, as steam jets up from small cracks in the now-hardened lava-lake’s surface and the minute specks of hikers cross its black expanse, but the crater today is more than a mile long, 3000 feet across and almost 400 feet from the rim to the surface. At it’s peak, the volcano spewed about two million tons of lava per hour; however, between spurts, much of this liquid drained back into the subterranean plumbing of the caldera, thus giving the distinctive “ring-around-the-crater” look to Kilauea Iki.

The active vent for these eruptions was at Pu’u Pua’i; you can go here for more information on the Pu’u Pua’i eruptions. The hike down into, and across, Kilauea Iki is perhaps the best short hike in the park. Go here to find out more on making this spectacular, but fairly easy, trek.
